Fast Keyword Spotting from Acoustic Baseforms
Original language description
This paper describes a filler model, used in our keyword spotting system, which is implemented as a phoneme recognizer. The filler model produces a sequence of phones corresponding to the input utterance and can be used as a phoneme recognizer. The dependency of accuracy and correctness on the filler model back loop penalty as well as the influence of the filler model language model are depicted. The output of the phoneme recognizer can be used for keyword spotting. Two modifications of basic DTW algorithm are presented. The advantage of this keyword spotting approach is the possibility of two pass detection. The first pass (slow) is done only once. The second pass (fast) is done on the request of searching the keyword and uses only the sequence of thephones generated by the first pass. All the tests are performed on the telephone speech corpus.
